MAGAZINE LUBRICATING SYSTEM.

Application filed June 1, 1925. Serial No. 34,015.

This invention relates to means for lubricating bearings of various kinds and 1s particularly adapted for use in connectlon with automotive vehicles.

In my Patent 1,620,277 issued March 8,' 1927, I have set forth the advantages of oil lubrication for the chassis of automotive vehicles and have pointed out in said application how the oil, which is drained from the crank case of the vehicle may be utilized in various magazines or reservoirs distributed at difi'erent parts of the vehicle for lubricating the surfaces closely adj acentsaid magazines.

It is the object of my present invention to provide an improvement on said patent as Well as on the arrangement disclosed in my Patents 1,314,689 issued September 2, 1919, and 1,387,295 issued August 9, 1921.

In the above mentioned patents, I have disclosed individual, or, local magazines or reservoirs for containing oil with means within said magazines for feeding oil to the surfaces to be lubricated. In each case, the individual magazines are provided with caps or filling means by which oil may be put into the magazines. In ordinary practise I have found that these magazines need filling only three or four times a year, but, in order to eliminate even this amount of work and to insure that the local magazines are continuously provided with oil, I have, in my present case, provided a common, or, central reservoir of suitable size which may be filled with new oil, or as mentioned in my Patent 1,620,277, with the oil drained or taken from the engine crank case, it being the well es tablished practise to drain the oil from the engine crank case at stated intervals and renew with fresh oil. It has been found that in practically all cases, there is still a large amount of lubricating qualities still left in oil taken from the engine crank case, and instead of throwing this away, I propose to use it for lubricating the parts of the chassis.

My present improvement will best be understood by reference to the drawing, in

- which,

Figure 1 illustrates one side of the front end of a vehicle chassis showing the common Figure 2 is an enlarged view of one of the local reservoirs shown in Fig. 1.

Figure 3 shows a local magazine for at tachment to .a member having a surface to be lubricated, substantially the same as illustrated in my copending application, Serial No. 9,727 filed February 17, 1925.

Figure 4: is a fragmentary View showing the front end of an automotive vehicle illustrating means for filling the common or central reservoir from the engine crank case.

In the various figures wherein like numbers refer to corresponding parts in the various views, 1 is a side member of a chassis of an automotive vehicle; 2 is an axle on which is carried the usual spring 3. To the member 1 is attached a plate a carrying an oil magazine 5 having a cap screw 6, which, according to the disclosure of my Patent 1,314,689 already referred to, was for the purpose of filling the magazine, but in the present case, it is used only for inserting the wick 7 carried in tube 8 leading to a-spring bolt carried in a hole 9. In the present case, oil is fed to the local magazine 5 from a common or central reservoir 10 which may be mounted in any satisfactory place on the vehicle, but preferably above the level of the highest local magazine so that oil may feed by gravity through the pipes 11 to the local magazines 5. As shown in Fig. 2, the pipe 11 extends into the magazine 5 for some distance, and since the oil chamber of the magazine 5 is made air tight above the oil level, the oil level therein will be maintained at the same level such as 12. As the oil in each individual. magazine, 5' is used up b being fed through the wick 7, additional 011 is supplied from the common reservoir 10 in a manner well understood.

It is to be further understood that while I have shown in Fig. 1, only two local magazines 5, there is a number of these at various parts of the vehicle requiring lubrication and that the system of plplllg from the reservoir 10 may be of any satisfactory kind, although, the pipes used should be of a size as to insure a non-obstructive flow between the common reservoir 10 and the local magazines 5. By

either continuously or intermittently,

tached to the member 14 by passing the member'13 through an opening closed by a cap 17 all as disclosed in my application Serial No. 9,727 hereto referred to.

The common reservoir. 10 is preferably of a size suificient to contain oil enough to maintain a supply to the local magazines for a considerable period of time.

In Fig. 4 I have shown a pump 18 having a suction line 19 running to thesump 20 of the crank case of the engine 21. From the pump 18 a discharge line 2-2 extends to the common reservoir 10 which is preferably provided with an over-flow pipe 23 carrymg the surplus oil back to the engine crank case. As shown in Fig. 4 the pump 18 has a manual type of control for pumping the oil from the engine crank case to the reservoir 10. In this arrangement, the reservoir 10 is preferably provided with a visual indicator 24 to indicate to the operator the level 25 of the oil in the reservolr 10. It is obvious that a pump operated by the engine or moving part of the vehicle may be llisetd u a since the consumption of oil in my present system oflubrication is economical, I find that it is desirable to use only the intermittent arrangement. It is to be understood that the pipe 19 so connects with the sump 20 of the engine that there will always. be some oil left in the engine crank case for lubrication of the engine, which, is usually provided with its own indicating gaugeto show the amount of oil in the engine.

It is to be remembered that while the oil taken from the engine crank case may have,

and usually does have, certain solid impurities in it, the wicks 7 act as filters so that only the lubricating oil is carried to the surfaces to be lubricated.

It is to be understood that the main reservoir and magazines may be provided with drain plugs so that they may e cleaned out whenever necessary. With this system of lubrication, it will be seen that a considerable quantity of oil is carried at each local magazine and that these magazines are automatically replenished with oil from the common reservoir according to the needs of each, without any reference to any of the other magazines. This system thus provides a large reserve of lubricant in the local magazines even should the supply in the main azines b means of a piping system through which 011 may be forced from time to time by means of a pump attached to some source of lubricant supply as the alternative for the gravity feed shown in Fig. 4. It is obvious that a cut-offvalve may be placed in the main feed line 11- from the common reservoir 10' so that the supply of oil to the various magazines may be cut off completely if desired. j

While I have disclosed in a more or less diagrammatic manner the way in which my invention may be put into practise, it should be clearly understood that the details may be varied over a considerable range without departing from the spirit of my invention or the scope of the appended claims.
